Compatibility IssueNikon has posted its own compatibility chart, Nikon Rumors and Adobe have also chimed in. The problem lies within Nikon's libNkPTPDriver.dylib, which serves to communicate from the DSLR through the OS, and to the host application. Nikon's PTP library uses an outdated Apple framework call (ICARegisterEventNotification), which has been removed in OS X 10.11.

As a personal desktop system, El Capitan may offer new and usable features. As a production system in your photo chain, however, it only serves to break your Nikon compatibility. Our users are advised to use OS X 10.10 and not make the leap to El Capitan, at least not until Nikon and Apple have a solution.

We've already had a few users who have dove into OS X 10.11, only to find themselves completely frustrated. Avoid the temptation- we have no choice but to wait for Apple and Nikon to sort this out.

What to ExpectBoth Nikon and Canon have been working to deliver 64-bit compatible libraries (Nikon has recently done so), which will allow us to move full-force into native 64-bit versions of SnapShot Studio. This isn't a simple process for anyone-Nikon, Canon, Apple, Microsoft, us, or you. Older hardware will not be compatible moving forward. For Windows versions of Allen Christopher titles, we will be forced to provide 32 and 64-bit versions of our software. For Mac users, 64-bit will be the only option.
